MACHINE FOR SPREADlNG MANURE.

SPECIFICATION forming part of Letters Patent No. 308,064, dated November 18, 1884. Application filed March 20, 1884. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM HALLIBUR- TON ORANDALL, of Stow, in the county of Middlesex, of the Commonwealth of Massachusetts, have invented a new and useful Improvement in Machines or Vehicles for Spreading Manure or Fertilizing Material; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which Figure 1 is a top view, Fig. 2 a rear end View, Fig. 3 a front end View, Fig. 4 a longitudinal section, and Fig. 5 a side elevation, of a manure-spreader provided with my invention, the nature of which is defined in the claims hereinafter presented.

In such drawings, A represents a cart-body resting 011 a bent axle, B, as shown, having two wheels, 0 G. The tail-board D of the cartbody, at or near its upper corners, is pivoted to the said body, so as to be capable of being swung outwardly therefrom. From such tailboard, at one end of it, an arm, a, projects upward, and is pivoted to a long bar, 1), arranged as shown, .and having a handle, 0, at its front end, and just in rear of such handle a series, d, of holes, to engage with or receive a stud, 6, extending upward from the cartbody. The bottom of said cart-body is a movable onethat is to say, it is an endless floor or apron, E, suitably made, and supported on wheels or rollers, so as to be capable of being revolved, like other endless aprons, there being fixed on the shaft of its front roller or roll ers a ratchet-wheel, f, to be actuated by a draw-pawl, g, pivoted to lever h. This lever is fulcrumed to one side of the cart-body, and at its rear end carries a friction-roller, a, over and upon which is a rotary toothed cam, k, fixed to the hub of the wheel 0. While the said wheel may be in revolution the cam will reciprocate the lever, so as to cause the drawpawl to intermittently revolve the ratchetwheel, and in so doing effect a movement of the endless apron, to carry any manure,when on it, toward the tail-board. Directly in rear of the endless apron is a toothed cylinder, F, Whose shaft is supported in bearings in extensions Z Z from the cart-body, and has fixed on it a pinion, m. A gear, 02, attached to the hub of the other wheel, 0, engages with a gear, 0,

revoluble on a stationary arbor, 1), that has upon it another and larger gear, q, provided with a clutch or teeth, 7", to clutch it to the gear 0, the latter having holes for the teeth to: 5 5

enter. To the hub of the other gear, q, there is fixed a peripherically-grooved wheel, 8, into the groove of which a furcated lever, t, extends, such lever being arranged as shown,

and fulcrumed to the side of the cart-body.

a connecting-bar, x, jointed to them, its intermediate arm having jointed to it another lever, y, fulcrumed to the'front end of the cart-body, and extending underneath the front arm of the lever h. On taking hold of the uppermost arm of the tri-armed lever and moving it inwardly the gear q will be unclutched from the gear 0. Simultaneously the lever It will be moved so as to carry its draw-pawl out of engagement with the ratchet-wheel and the friction-roller of such lever Z far enough below the cam 70 to prevent such cam,while revolved by its wheel, from operating the lever.

From the above it will be seen that'the toothed cylinder has mechanism for revolving it by one of the cart-wheels; also, that the endless apron has mechanism for revolving it by the other cart-wheel, and that these mechanisms are furnished with means by which they may be thrown out of action, in order that the cylinder and apron may be at rest relatively to the cart-body when it may not be desirable to have any manure or fertilizing material discharged therefrom.

The driver-s seat is shown at H, the cartbody having a tongue, or such and forward wheels, if required. The seat is so situated as to enable the driver to readily applyihis right hand to either the tri-armed lever 10, or to the working-bar b of the tailboard D, to operate the same, as occasion may require.

By means of the workingbar, perforated with holes, as shown, such bar can be adjusted on the stud 0 so as to incline the tail-board more or less, to vary the amount of discharge of the manure or material from thelendlessl floor or apron of the cart-body.

On the cart-bodybeingladen with manure and the tail-board moved backward and the cart I F, arranged below such tail-board, whereby startedahead, 'the manure, by the apron, will be discharged upon the toothed cylinder,which being in revolution will throw the manure against the tail-board, and in so doing break up and scatter such manure and discharge it downward upon the ground.

The delivery of the manure can be regulated by means of the adjustable tail-board, the holes in the operative bar of which may be marked to indicate the number of loads required per acre; the machine will discharge when either hole is on the stud e.

p I claim 1. The tail-board D, hinged at the top to the wagon-body, the bar b, having holes d, and the pin a, in combination with the toothed roller such tail-board can be adjusted todiiferent positions, so that the manure can be passed between it and the roller, as set forth.

2. The endless apron E, its operative mechanism, consisting of pawl h, ratchet f, and cam is, and the toothed roller F and its operative mechanism, consisting of the gearing and its shipper-lever t, in combination with the triarmed lever to and the connecting-arms y and 7 to, all combined, arranged, and constructed as and for the purposes set forth.
